Waste plastics come in a wide variety, with significantly different cracking temperatures and reaction rhythms among materials. Conventional high-temperature cracking modes easily cause excessive carbonization of some lightweight plastics and increased material loss, making them unsuitable for mixed-feed production scenarios. A mild and stable low-temperature cracking process matches the reaction characteristics of diverse materials and supports the coordinated disposal of multiple categories of waste plastics. Henan Yongle Group has optimized the low-temperature controllable cracking process of its plastic refining equipment based on the physical and chemical properties of various plastic materials, regularizing the pyrolysis reaction rhythm while supporting diversified material production and optimizing material conversion results.

The plastic refining equipment is equipped with a controllable low-temperature cracking system that relies on a precise temperature control system to lock in the appropriate reaction temperature range, avoiding material over-oxidation and carbonization caused by high-temperature conditions. For loss-prone materials such as film plastics, packaging plastics, and soft plastics, the effective components can be fully preserved, improving material conversion and utilization.

This process requires no fine classification and screening of raw materials, and can handle household waste plastics, industrial waste plastics, mixed miscellaneous plastics, and other materials. It matches the raw material supply conditions of small and medium-sized recycling plants and simplifies early material sorting.

The low-temperature cracking reaction rhythm is gentle, with no severe fluctuations in furnace conditions. Oil-gas is released uniformly and steadily, effectively reducing the generation of heavy smoke and sticky heavy impurities, lowering the processing load on downstream condensation and purification systems, and extending the service life of supporting consumables.

The stable low-temperature reaction environment reduces coke and carbon deposits inside the furnace walls and pipelines, slows equipment wear, extends intervals between shutdowns for cleaning, effectively increases the effective operating time of the production line, and suits normalized continuous production.

The highly adaptable low-temperature cracking process broadens the material applicability of the plastic refining equipment, addresses production weaknesses in mixed material disposal, makes the waste plastic resource recovery process better suited to actual production scenarios, and supports the steady development of the solid waste recycling industry.
